Describe the feature

Introduce the dynamic disk selection for one partition in LOCALFILE, especially when some disks reached the high-watermark.

Motivation

Currently, when mounting multiple disks in shuffle-server and using the MEMORY_LOCALFILE storage type, one app has a very large partition data and its selected disk reaches the high watermark, it will preserve the data into the memory. This will make some app hard to get the memory.

Describe the solution

Maybe we should let the its partial big partition data store to the another disk.

If you use MEMORY_LOCALFILE_HDFS, it won't be a big problem.

Yes. This is an optional solution.

Actually we ever use raid disk to solve this problem when we only have localfile mode.

@jerqi As the raid disk has been tested and shown that there is performance degradation while using raid0/LVM. I will pick this issue up to implement a multiply disk store approach for one partition.
